I am a beginner, but i have managed to develop a 2 digit seven segment display.I am utilizing an external 12vdc power source, max7219, common anode digits, source driver and sink drivers.I have been developing source code to scroll through 0 to 99. Unfortunately i go from 00 to 01 then i am out of the loop and nothing else happens. I have been through the arduino foundations, tutorials etc... . But I still can not figure out what I am doing wrong. Maybe somebody can lead me in the right direction to get this to work.(I hope my code is posted correctly, my first time for posting).I can set "v" to any value and it displays correctly.Thank you in advance.

LedControl lc=LedControl(12,11,10,1);unsigned long delaytime=200;// v*75void setup() { /* The MAX72XX is in power-saving mode on startup, we have to do a wakeup call */ lc.shutdown(0,false); /* Set the brightness to a medium values */ lc.setIntensity(0,8); /* and clear the display */ lc.clearDisplay(0); int v = 0;}void loop()

LedControl lc=LedControl(12,11,10,1);unsigned long delaytime=200;// v*75void setup() { /* The MAX72XX is in power-saving mode on startup, we have to do a wakeup call */ lc.shutdown(0,false); /* Set the brightness to a medium values */ lc.setIntensity(0,15); /* and clear the display */ lc.clearDisplay(0);}void loop() // function to send digits to 7 seg led{ for(int v=0;v<100;v++) {

What's this all about ?The loop variable is v and you presumably want it its value to go from 0 to 99 but you change its value inside the for loop, not just once but twice. If you need the value of v/10 for some reason then put it in another variable to avoid messing with the operation of the for loop.

Please do not send me PMs asking for help. Post in the forum then everyone will benefit from seeing the questions and answers.
